MetabolomicsGREM1 Deficiency induced Bone Marrow Adipose Niche promotes B-cell Acute Lymphoblastic Leukemia Disease Progression
Relapse and disease progression are the primary causes of treatment failure and subsequent mortality in children B-cell acute lymphocytic leukemia (B-ALL). At diagnosis and during treatment, the bone marrow adipose microenvironment is commonly observed in pediatric leukemia. However, the relationshi...

MetabolomicsImpact of acute lymphoblastic leukemia induction therapy: findings from metabolomics on non-fasted plasma samples from a biorepository

INTRODUCTION: Acute lymphoblastic leukemia (ALL) is among the most common cancers in children. With improvements in combination chemotherapy regimens, the overall survival has increased to over 90%. However, the current challenge is to mitigate adverse events resulting from the c...

TranscriptomicsRNA-seq of primary human bone marrow derived mesenchymal stromal cells from pediatric B-cell acute lymphoblastic leukemia (B-ALL) patients
To investigate the identity of the tumor microenvironment in acute lymphoblastic leukemia (B-ALL), the transcriptome of mesenchymal stromal cells derived from bone marrow of three pediatric patients at the onset of the disease was analyzed and compared with its normal counterpart.

TranscriptomicsPax5 restoration in a mouse model of B progenitor acute lymphoblastic leukemia
Hypomorphic mutations of PAX5 occur in one third of B-progenitor acute lymphoblastic leukemias (B-ALLs), however their functional consequences remain undefined. Here we employ advanced transgenic RNAi in mice to suppress endogenous Pax5 expression in the hematopoietic compartment in vivo, which co-o...

TranscriptomicsRearrangement of CRLF2 in B-progenitor and Down syndrome associated acute lymphoblastic leukemia
Chromosomal aneuploidy and translocations are hallmarks of acute lymphoblastic leukemia (ALL), but many patients lack a recurring chromosomal alteration. Here we report a recurring interstitial deletion of the pseudoautosomal region 1 of chromosomes X and Y in B-progenitor ALL that results in the ex...

TranscriptomicsThe HDAC inhibitor panobinostat (LBH589) inhibits Acute Lymphoblastic leukemia (ALL) in vitro and in vivo in a new characterized human ALL mice model (ALL-B and ALL-T)
Histone deacetylases (HDACs) have been identified as therapeutic targets due to regulatory function in DNA structure and organization. We have analyzed the role of the LBH589, a novel pan inhibitor of class I and II HDACs, in Acute Lymphoblastic Leukemia. In vitro, LBH589 was shown to induce a dose...

TranscriptomicsRole of miR-125b in B-cell acute lymphoblastic leukemia (B-ALL)
B-cell acute lymphoblastic leukemia (B-ALL) is often associated with chromosomal translocations leading to the deregulation of proto-oncogenes. MicroRNAs can also be affected by chromosomal alterations and thus contribute to carcinogenesis. The microRNA miR-125b-1 is over-expressed in B-ALL cases wi...

TranscriptomicsThe Methylome Landscape of Infant B-cell precursor Acute Lymphoblastic Leukemia (iB-ALL)
B-cell acute lymphoblastic leukemia (B-ALL) is the most prevailing childhood cancer. As predicated by its prenatal origin, infant B-ALL (iB-ALL) show a silent mutational landscape irrespective of the MLL rearrangement/status, suggesting that other regulatory mechanisms might be impaired in the conte...

TranscriptomicsmiR-126 Orchestrates an Oncogenic Program in B-Cell Precursor Acute Lymphoblastic Leukemia
MicroRNA (miRNA)-126 is a known regulator of hematopoietic stem cell quiescence. We engineered murine hematopoiesis to express miRNA-126 across all differentiation stages. Thirty percent of mice developed monoclonal B cell leukemia, which was prevented or regressed when a tetracycline-repressible mi...
